BLM放牧規制95年ぶり改正 市民参加を制限へ

The federal government is rewriting its rules governing ranching on public lands to increase the number of cattle, sheep, and other livestock grazing on 155 million acres in the West, an area twice the size of New Mexico. Public lands grazing is overseen by a nearly century-old system that heavily subsidizes some of the wealthiest Americans while doing little to address its harms to the environment, ProPublica and High Country News found last year. Even though rangeland management experts say overgrazing has degraded public lands, the new rules being drafted by the US Department of the Interior’s Bureau of Land Management—the first overhaul since 1995—would instead expand the practice. The proposed rules would also ratchet back public participation in the agency’s decisions to allow grazing on federal public lands.

The BLM’s proposed updates would strictly limit who has a say and when they can object, eliminating many steps where the public has been able to observe and comment on decisions to issue or renew permits. “They’re clearly trying to reduce involvement of anyone other than ranchers,” said one BLM employee who works on rangeland management. The BLM did not respond to questions about the proposed regulations, which were released publicly in May and, after a period for public comment, will go back to the agency in mid-July for further review. In a June news release announcing the action, the agency said it “reflects the Trump administration’s priority to reduce unnecessary regulatory burdens, promote productive working lands and strengthen local economies.”

The employees agreed that the updated regulations offer several concrete benefits, including a requirement that the agency study the ecological impacts of all uses of public lands—from timber harvesting and recreation to mining and oil drilling. The current rules limit such reviews to the livestock industry, where they have uncovered tens of millions of acres of damage due to overgrazing.

編集部の見解

今回の改正案が提起する最大の論点は、プロセスの効率性と民主的参加のバランスである。短期的に見れば、放牧業者にとって規制の予測可能性が向上し、許可更新の迅速化が期待できる。環境影響評価の対象が全土地利用に拡大された点も、データ駆動型管理への移行として評価できる。しかし、市民参加の後退が環境監視の質低下を招けば、長期的には生態系劣化のリスクが高まる。中長期的には、気候変動と水資源不足が西部諸州で深刻化する中、公有地管理の透明性が低下すれば、社会的受容性を損なう可能性がある。行政の効率化と市民参加のトレードオフは、デジタル時代のガバナンス全体に共通する課題だ。BLMが管理する約1億5500万エーカーのデータ量を考慮すれば、手続きの効率化自体は合理的と見る。ただし、環境NGOや地域コミュニティの異議申し立て機会が実質的に機能しなくなるのであれば、規制の実効性そのものが問われることになる。
